[. . . ] E-Z KEY CMOS CW KEYER Ramsey Electronics Model No. CW7 Add to your CW fun with this low cost keyer kit. You'll send clean code that's a pleasure to copy!· · · · · · · · · Works great on any transmitter Built-in sidetone oscillator with pitch control Front panel volume and speed controls Clear, concise assembly instructions carefully guide you to a finished kit that works the FIRST time! [. . . ] Set R2 in the approximate center of its total rotation. Turn R1 fully clockwise (maximum speed). Begin sending something familiar and repeated such as CQ. With the small screwdriver in your other hand, adjust R2 until your sending speed is the maximum that you ever expect to really use, at least for the time being. 5. While still sending CQ or your callsign, slowly turn Speed Control R1 counter-clockwise. If you reach the slowest speed you expect to be using with room to spare, then your adjustment is complete. "CONFIGURING" YOUR OPTIONS FOR: AUXILIARY J3, AUDIO OUTPUT, AND EXTRA SWITCH CONTACTS: There is NO one "best" way to set up the auxiliary functions of an electronic keyer. That's why some flexibility is pre-designed into your CW7. You can use and change the possible functions of the audio output, J3 and the SPDT section CW7 · 15 of the power switch without affecting the basic terms of the Ramsey Kit Warranty or the market value of your CW7. Auxiliary Jack (J3) This jack does nothing unless you MAKE it do something!Here are some of the typical ham shack functions to which it may be applied: Wired in parallel with J1 for: · connection to 2nd transmitter or transceiver · input of auxiliary CW straight key · input of computer CW keying interface Wired to speaker output connections for: · external speaker · connection to external audio amplifier input Wired to S1 for: · controlling another DC low-voltage hamshack accessory in either on or off mode for the keyer itself. Other applications are easy for both you and us to conceive. There is no need to do anything with J3 until you decide how it will help you the most. Sidetone Audio Output (2 holes near Q3) The sidetone may be fed to a small speaker within the CW7 enclosure, to auxiliary jack J3, through other wiring, or can be simply ignored or not used. That's right: use it IF you need it, and don't use it if your transceiver already generates a preferable sidetone. The CW7 sidetone is a convenience option designed to help beginners enjoy this unit as an upgraded "code practice oscillator" and to provide sidetone monitoring for Ramsey QRP transmitters. If you don't need it with your transceiver, don't use it - and you will not hurt our feelings!Extra SPDT pole on POWER ON-OFF SWITCH For this switch, a couple of extra PC-board solder pads are provided for the power-on ("in") position. In addition, the solder connections on the top side of this switch are all accessible and usable. If you want to turn some other station accessory on or off when you switch on your CW7 keyer, this switching convenience is available to you. One practical function is for its second pole to key your transmitter for tune-up when the keyer power is in the off position. CW7 · 16 "MESSAGE MEMORY" FOR YOUR CW7 KEYER While there are obviously no built-in memory functions in the CW7, today's hams do well to recall that "memory keyers" were designed out of necessity by late 1970's contest enthusiasts, preceding inexpensive personal computers by several years. There are hundreds of programs, for every operating system, every programming language and every imaginable computer, which let you send pre-programmed CW texts of ANY length with one keystroke.
